BRAKE MECHANISM- To all ivhom it may concern: A Be it known that I, HANS THEODORE HAN- emit, a citizenof the UnitedIStates, residin at Milwaukee;

county of Milwaukee, an State of W isconsinf have invented new and useful Im rovements in Brake Mechanism,

and showing a portion of the axle.

of which t e following is a specification.

My invention relates to improvements in rake mechanisms for steering-wheels which are swung to nan axis in the plane of he wheel. The object of m invention is to provide suitable brake mec anism for wheels of this Tn the following description reference is had to th which Figure 1 is avertical sectional view of an automobile-wheel embodying my invention Fi 2 is a view of the-fa cc of the wheel, showin g the axle-driving shaft and brake-operating rod in cross-section. Fig. 3 is a plan view 01" the e accompanying drawings, in

parts shown in Fig. l with the Wheel partially broken away.

\ Jlke parts are identified by the same reference characters throughout the several views.

1 is a stationar tubular axle of a motordrivenvehicle. his axle is provided with trunnions 2 at its outer extremlt-y, occupying apositionin'the vertical axis of wheel oscillation. I

3 is an oscillating ring pivotally mounted on the trunnions 2, and this ring supports the wheel 4, which is mounted to turn on the os-. cillating ring, with interposed ball-bearin s 5. The wheelrs. driven from any suitab emotor carriedon the vehicle through a shaft- 8, connected by universal joint 9 with an inwardly-extending "ortion 10 of the wheel. These parts may al be of any ordinary construction suitable for the purpose.

he inner face of the wheel is provided, with an annular shoulder 12 and a split ring 13 is adapted when s read to bear against the inner face of this s oulder. The ring 13 is supported from the oscillating ring 3 by an arm 14, with which the split ring '13 is pivotally connected at 15, so that wheri the r1ng-13 is spread it serves as a band-brake for the Wheel. The ring 13 being supported from the oscillating ring 3 it is obvious that it will swing with the ring 3, and therefore maintain its relation to the wheel and the shoulder 12 Specification of Letters Patent.

thereof. The rin 3 is swung to oscillate the wheel by means o a steering-lever 16, and as the split ring 13 is mounted thereon it is adapted to serve as a brake for the wheel in any position of steering adjustment. To set the brake, the ring 13 is spread by means of a lever 20, from which motion is communicated to the ring 13 through a rock-shaft 21, arm 22, segment 23, post 24, and links 25, the latter being pivotally connected at 26 and 27 with thepost and ring 13, respectively. The links are connected with the ring 13 at opposite sides of the point of division 28, whereb an upward movement of the arm 22 will li t the post 24 and cause the two halves of the ring to spread under the outward pressure of the links 25, which serve as a toggle. The links are referably in sections connected by turnbuck es 30, whereby they may be nicely adjusted in length.

The arm 22 is preferably rovided' with an antifriction-roller 32, which bears against the segment 23. The post 24 is guided by a sleeve 33, supported from the oscillating ring. The part 23 is termed a segment by reason of its function, which is to provide a bearing-surface for the roller 32 through. the segmental arc in which this portion of the wheel oscillates when the wheel is swung for The required size of this steering purposes. segment is dependent upon the distance of thepost 24 from the axis of oscillation. A post 24 at the axis of oscillation would require no enlarged hearingsurfaoe. Owing to the elongated bearing provided by the sleeve 33 the post 24 will be pushed upwardly without binding when u ward pressure is applied to any portion of the segment 23.

g It is of course to be understood that each of the steering-wheels of the vehicle may be similarly equipped with a brake and brakesetting mechanism, and the brake-operating lever may be connected to any suitable point for manual control.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,

1 In a motor-driven vehicle, the combination with a'steering-wheel, pivotally supported substantially in avertical lane thereof, and driving connections flexib y jointed substantially 1n the same plane, of a brake car- .ried by the Wheel-support; a brake-operating zoo member swinging with the brake and wheelsupport about said "pivotal axis; on actuating member mounted upon the 'el]icle-trerne at one side of the axis of the wheel-pivot and adopted to transmit motion to the operating member in various positions of wheel-adjustment.

2. In e 1noto1'.-d1iven vehicle, the co1nbine' tion with a steering wheel, pivotully support ed substantially in a vertical plane thereof, and at relatively stationary axle provided with e pivoted wh el-supporting member, of e brekecsrried by said wheel-supporting member-in operative relation to the wheel; a brel-1e-opereting member mounted upon the wheel-supporting member at one side of said pivotal end a brakeutctuuting member movebly mounted on the relatively stationary exle at one side of said pivotal axis and adapted to transmit motion to the brake-operating member in vorious positions of wheeledjustment 3. The combination of a relatively stationn-rj support, it pivotally-swinging nOlbIObUr table support connected therewith, e wheel mounted on seid swinging support in a plane eutting its pivotal axis, a brake located at one side of said plane and connected with the St- 'nging support, brekooperating mechanism mounted upon the swinging supgort at one side oi the pivotal axis, and actuating mechanism on the stationary support, :11- renged to engage and actuate the operating mechanism at various points in its ere oi osoiiiution.

4. in e motor-driven vehicle, the combination with e relatively stationery axle, u wheetsupporting member pivotelly connected therewith, wheel mounted on. said member substantially in the piene of its pivotal connection "with suid axle, and driving conii isior said wheel, flexibly jointed, sub s t all in the )lane of the wheel, of at bandbrelie supportev from said wheelsupporting member in operative relation to said wheel; a

post having sliding bearings in the Wheel-supporting member, and toggle connection with the bra-lie; and brake-actuating mechanism mounted on stud axleat one side oi the wheel,

and adopted to communicate motion to said 7 ing-surlnce adapted to be engaged by said brake-actuating member at various points in its arc oi" oscillation.

(5. The combination-of a, relativelystation-- cry axle; u swinging support pivotally connected therewith a wheel rotatably mounted on said swinging support; it broke connected with said swinging support; a brake-operating member mounted on said swinging support; and provided with an elongated guide bearing thereon an actuating member mountul on the relu-tively stationery support and adapted to conm'iunicete motion to the o, utiug member, said members being uncon nected, and said operating member being pro-- Vided with a segmental bearing surface, curved in the are of oscillation of the operating member, and adopted to be engaged by the actuating member in various positions of relative adjustment.
